Sky & Telescope’s 2025 “Galileo’s Italy” tour offered much more than sightseeing, as participants enjoyed multiple opportunities to stand on astronomical hallowed ground.

The post In the Footsteps of Galileo appeared first on Sky & Telescope.

We know lots about our Galaxy yet still, some regions still hold countless secrets. Recently, a team of astronomers using South Africa's MeerKAT radio telescope uncovered 164 of them, compact radio rings. Each one smaller than an arcminute across, were hiding along the plane of the Milky Way, and were just waiting for a telescope powerful enough to reveal them.

For millions of years, a fragment of ice and dust drifted through interstellar space, its origin, a distant planetary system. This summer, that fragment finally entered our Solar System, becoming only the third confirmed interstellar visitor and earning the designation 3I/ATLAS. When astronomers at Auburn University pointed NASA's Swift Observatory toward this icy chunk, they detected water vapour streaming from its surface. It was revealed through the faint ultraviolet glow of hydroxyl molecules and was completely unexpected.
